Always the Blues, always Diego Costa

After scoring a stunning 27 goals in La Liga in 2013-14, behind only Cristiano Ronaldo and Lionel Messi, and firing Atletico Madrid to a historic league triumph, Diego Costa is taking on the challenge of excelling in the English Premier League.

The Spanish international striker joined Chelsea in the summer of 2014 with Jose Mourinho eager to add his power, pace, determination and cutting edge to the Blues attack.

Costa could be the missing piece of Chelsea's championship puzzle, and if they are to lift the EPL title at the season's end, his goalscoring exploits will be a big reason.
